Description
Technical field
The present invention relates to field of intelligent control technology, be specifically related to a kind of Based Intelligent Control environment-friendly type waste or used plastics energy-saving recycling preparation system.
Background technology
Along with industrial expansion, the application of plastic products is throughout the every field of industrial or agricultural and daily life, the waste or used plastics rubbish of whole world generation every day cannot be estimated, but its large pressure of tool caused environment is apparent, in order to process these plastic garbages, existing method is generally landfill, burning etc.But because the natural degradation of common plastic garbage is chronic, generally will could degrade through more than 100 years, and also can produce the harmful substances such as a large amount of methane in degradation process, therefore landfill method has obtained denouncing of a lot of expert; And pernicious gas, flue dust etc. that burning method produces directly impact environment.Simultaneously because plastics are as petroleum chemicals, its primary raw material produced is oil, and it is a kind of non-renewable resources, and current Global Oil contention is more and more fierce, crude oil cost is more and more higher, and therefore recycling for plastic product is the best approach solving plastic garbage problem at present.
The recovery method of waste or used plastics is divided into physiochemical mutagens method and chemical recycling.The main method that current polyethylene is recycled is chemical recycling, namely under the existent condition such as chemical reagent, catalyst, heat, polyethylene degradation is become the oligomer that can re-use or micromolecular compound, thus realizes recycling of discarded object.But in recovery granulation process, inevitably produce tail gas, if directly discharge, pollute the environment.
In prior art, smoke collection pipe is directly connected exhaust filtration devices by air-introduced machine, exhaust filtration devices connect chimney, filtered flue gas with chimney directly discharged to sky.The mode of this filtration still can remain the pernicious gases such as a large amount of sulfide, and produces a large amount of carbon dioxide, and earth surface temperature is increased, and produces greenhouse effects.
Moreover traditional waste plastic regeneration production line adopts artificial material, artificial start etc. on hand, and in production process, manually-operated danger is high, and labour intensity is large.
Summary of the invention
It is simple, reasonable in design that technical problem to be solved by this invention is to provide a kind of structure, realizes the Based Intelligent Control environment-friendly type waste or used plastics energy-saving recycling preparation system of Automated condtrol.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of Based Intelligent Control environment-friendly type waste or used plastics energy-saving recycling preparation system, comprise the magnetic roller type plastics magnetic separator de-ironing connected successively, plastic screen look machine, fully automatic feeding feeding all-in-one, dual four layers are filtered soot blower, air-cooled without the fervent die head of net and plastic extruder, waste or used plastics directly enters magnetic roller type plastics magnetic separator de-ironing and carries out deironing after pulverizer is pulverized, remove metal impurities, plastic screen look machine is sent into again through conveyer, after sieve look, the plastic grain of solid color sends into fully automatic feeding feeding all-in-one respectively by conveyer, plastic extruder is sent into by fully automatic feeding feeding all-in-one, extrude without the fervent die head of net through air-cooled, wherein dual four layers of filtration soot blower are connected on plastic extruder, for the flue gas that filtering plastic extruder produces, also comprise the micro-control machine (PLC) being located at night shift room, described magnetic roller type plastics magnetic separator de-ironing, plastic screen look machine, fully automatic feeding feeding all-in-one, dual four layers of filtration soot blower, the air-cooled nothing fervent die head of net and plastic extruder are connected to micro-control machine respectively, accept the control instruction of micro-control machine, the parameter such as performance index, fault alarm of each equipment unit is all carried out being programmed into micro-control machine,
Unit starting only needs single by being controller operation, and during unit running, operator on duty detects the performance index of each equipment by micro-control machine, thus whether observe unit running normal; If micro-control machine display device conventional fault is reported to the police, unit can not shut down, and operator on duty can come warning device scene and check, checkout facility is normal, and operator on duty can be eliminated by micro-control machine and report to the police; If checkout facility fault, operator on duty manually stops unit, fault to be discharged, more normally starts unit by micro-control machine, eliminates warning equally; If micro-control machine display device risk of disturbance is reported to the police, unit can stop by self interlocking, again starts after fault to be discharged.
Described magnetic roller type plastics magnetic separator de-ironing comprises the first conveyer belt, described first top, conveyer belt charging one end is provided with aggregate bin, plastic products after pulverizing directly fall into aggregate bin, drop on the first conveyer belt again, described first conveyer belt is arranged at intervals with refining plate, plastic grain is tiled on the conveyor belt, described first conveyer belt discharging end is provided with a carrying roller, described carrying roller side is provided with magnetic roller, the built-in full magnetic block of described magnetic roller, described magnetic roller side is provided with cuts iron skewed slot, described section of iron skewed slot is that stainless steel is made, be with gradient, be close to magnetic roller, described carrying roller and magnetic roller one end are all connected to 0.75KW cycloidal needle wheel type motor by gear and driving chain, carrying roller is driven by chain drive, carrying roller drives magnetic roller by chain drive.
Operation principle: the plastic products after pulverizer is pulverized directly fall into aggregate bin, first conveyer belt upwards transmits, by way of refining plate, plastics are tiled on the conveyor belt uniformly, when by between carrying roller and magnetic roller time, under the effect of strong magnetic, tiny ironwork in plastics is attracted to magnetic roller surface, and plastic products fall and collect, the uniform rotation of magnetic roller, ironwork turns to thereupon and cuts iron skewed slot and scraped, then collects through smooth skewed slot landing.
Described plastic screen look machine will pulverize the sheet after deironing or particular plastics goods send into color selector through conveyer belt, via returning sequence passage finally piecemeal by main screening passage in color selector; Main screening passage is provided with a row sieve colour induction device, and the sheet chosen by sieve colour induction device or particular plastics can fall into from the bottom inlet automatically opened rapidly and collect cabin; Do not have selected will passing through, bottom inlet can not be opened, and then enters next inductor and carry out sieve look, and the slice plastic of such different colours will be fallen into by different sieve colour induction devices and different collect cabin, thus completes dithering and collect; Plastics after collecting enter fully automatic feeding feeding all-in-one again.
